Havelpol 4-UV + pure Polyester resin

Havelpol 4-UV + pure Polyester resin is light stabilized polyester resins containing styrene and methyl methacrylate. Its use is recommended in the manufacture of maximally clear manually GRP-produced film or casting and potting art objects. Fully cured laminates made from Havelpol 4 and powder associated mat of glass fibers "E" in quality for the production of films can exhibit light transmittance of more than 80%. They exhibit excellent resistance to weathering and stable appearance even after prolonged exposure.

The temperature of Havelpol 4 before use should reach a workshop temperature (18 ° C to 20 ° C). To start the curing reaction is necessary to add the catalyst and accelerator. The recommended catalyst is a peroxide K1 (or Butanox M50), which should add to the resin in an amount of 1-2%. The catalyst must be thoroughly dispersed in the resin and the mixture is usable for about 24 hours at the workshop (18 ° C to 20 ° C). Shortly before use, the catalyzed resin blended into the proper amount of the accelerator 1% cobalt in addition 0.5-1%. Attention! The catalyst and accelerator should not be mixed together directly, as they may react with explosive violence.

Weather resistance and light transmission: For maximum transmittance should laminates made using product Havelpol 4 show the ratio of resin to glass of at least 3: 1.

For optimum weather resistance and durability laminates must be fully cured. After shaping should laminates were aged at 20 ° C for at least three weeks before being circulated. Additional curing at elevated temperatures is not recommended.

Casting

It is a special section in which it is necessary to pay attention to its own findings regarding the dosage and temperature control. For casting procedures carefully the properties and we recommend to do any samples with various proportions of catalyst and accelerator.

Storage & Handling

Storage
  • The resin can be stored for at least 3 month in the carefully sealed containers at temperatures +20°C to +25°C.
  • Temperature should not be over +30°C. If resin create gel, do not use gel parts. Use only “liquid” resin.
  • Do not warm up over an open flame! While stirring up use safety equipment (gloves, eyeglasses, respirator).
